It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0017] As shown in the drawings, Figure 1As shown in the drawings, a plate flexible fixing mechanism comprises a bottom plate 1, a positioning structure 2, a clamping structure 3, a flexible support structure 4 and a support column 5. The positioning structure 2 is installed at both ends of the bottom plate 1 and is used for positioning and supporting both ends of the product. The support column 5 is installed at the middle of the bottom plate 1 and is used for supporting the middle of the product. The four clamping structures 3 are installed around the bottom plate 1 and are arranged close to the positioning structure 2 and are used for clamping and fixing the product to prevent the product from shaking during processing. The flexible support structure 5 is provided with six in this embodiment and can be adjusted according to the size of the product. The six flexible support structures 5 are sequentially installed on the bottom plate 1 and uniformly support the product to ensure that all parts of the product can be uniformly stressed, thereby preventing the product from being deformed due to self-weight or external pressure during processing or when placed on the clamp, reducing the influence of internal stress and external stress on the deformation of the product and improving the processing precision of the product.
